Know your role and shut your mouth!

The following are the roles of a female third or fifth wheel, as noted by Kat:

- Drink watcher
- Purse watcher
- Drunk tag-a-long entertainer (while your friends are kicking it with some cool guys, you get to hang around with the homie that is too drunk to remember his own name).
- Watcher of the pervos that try to cop cheap feels on your homegirl -- you note some asshole gettin' all touchy feely, your friend gives you that "help me" look, then you spring into "gurl, I got ur back action."
- Excuse for your friend(s) to not kick it with people they aren't clicking with. This is noted by, "Oh, I just want to spend some time hanging out with my homegirl," or "Oh, my girl has to work early in the morning, so we better leave."
- Cool guy judge -- if something is clicking, that extra wheel will let you know.
- Jerk-ass judge -- If homie sucks, they will let you know.
- Designated driver.
- In some instances, the spoiler -- if that extra wheel ain't having fun, or is being ignored, they will screw up everything. If you notice this, kindly pull to the side of the road, pop the trunk, and get out the spare. In other words, peace out bitchy bitcherson, and call another homegirl that isn't too far away.
- Drink getter.

I'm sure there are more, but these are just a few for now. Gotta love being the extra!
